摘要

As global energy demand continues to rise and environmental challenges become increasingly urgent, the pursuit of sustainable energy solutions has gained critical importance. This study employs Aspen Plus software to simulate the biomass gasification power generation process, investigating gasification efficiency, syngas composition, and its lower heating value under varying gasification temperature conditions. Additionally, the carbon reduction potential of the process is analyzed. The findings reveal that increasing the gasification temperature significantly enhances gasification efficiency and progressively improves the syngas’ lower heating value. At 1000 °C, the gasification efficiency reaches 86.7%, with a lower heating value of 13.5 MJ/m3. Elevated temperatures promote the generation of CO and CO2, while reducing the concentrations of H2 and CH4. Compared to conventional fossil fuel–based power generation, biomass gasification demonstrates notable carbon reduction benefits. Optimizing gasification temperature and process parameters can further minimize carbon emissions, aligning with low-carbon development goals. This study provides valuable technical insights and data support for the practical implementation of biomass gasification power generation, contributing to the advancement of renewable energy utilization and environmental sustainability.
